[00:04.140 --> 00:15.100]  Okay, so we're starting on time. And this is... let's see if I can do this... multiple cameras.
[00:16.420 --> 00:20.980]  So this is the... can you guess in this hour?
[00:26.280 --> 00:33.650]  This is the badge clinic. You almost can read that.
[00:35.430 --> 00:39.210]  So what will we talk about in this hour? We'll talk about badges.
[00:40.070 --> 00:41.950]  These things here.
[00:45.870 --> 00:51.590]  Yeah, so we'll probably see what they can... what we can do with this year's badge because it's
[00:51.590 --> 00:56.790]  kind of a storage device. So we can use it for backup and some other interesting things.
[00:56.790 --> 01:00.430]  Because it's an office hour, there is no set agenda.
[01:01.530 --> 01:05.670]  So we'll probably jump around a bit from different topics.
[01:07.030 --> 01:14.410]  And I will watch the... keep my eyes on the general text and the office text channels in case...
[01:15.230 --> 01:17.630]  in case there are some questions.
[01:19.490 --> 01:26.550]  Okay, so I guess you can see that this year's badge looks a little different than last year's badge.
[01:27.330 --> 01:33.890]  They're about the same size. This year we have no LEDs and no power supply. There's no battery
[01:33.890 --> 01:39.330]  inside this year. In place of that, we have a fine leather finish on the back
[01:40.650 --> 01:47.650]  with a plastic enclosure and a full color front overlay. And I'm just curious
[01:50.290 --> 02:00.140]  if audio is okay. I don't know which channel to type to. There's all these channels.
[02:00.140 --> 02:07.400]  Okay, so I'm not going to make any changes unless somebody tells me. So
[02:08.560 --> 02:12.700]  one of the things you can see in this year's badge, even though it does have
[02:14.620 --> 02:20.910]  a front overlay that usually covers all of the parts with color plastic is PET.
[02:22.140 --> 02:24.930]  So instead of seeing this, which is a PCB,
[02:26.250 --> 02:33.850]  you see this, which is a cover over a front overlay, full color printed. And in order to
[02:33.850 --> 02:38.910]  see these very small chips, which we thought would be interesting for all of the hardware
[02:38.910 --> 02:46.630]  hackers among us, we put in these transparent windows. All right, so let's take a look
[02:46.630 --> 02:49.850]  under the microscope at these transparent windows.
[02:51.910 --> 03:03.770]  Because I'm curious as well what this looks like. So this is the raw PCB with a
[03:03.770 --> 03:11.190]  EEPROM integrated circuit on top there, soldered in. And when we take a look at the
[03:14.410 --> 03:17.190]  color overlay, okay, this is going to need
[03:19.430 --> 03:26.530]  focusing and less illumination. Yeah, you can't see too well, can you?
[03:27.630 --> 03:39.570]  I guess because the light needs to be just right. Let's turn the light on again.
[03:39.570 --> 03:46.390]  Okay, so my experiment didn't work that well, but these are the EEPROMs that are
[03:46.390 --> 03:53.710]  storing our data this year. All right, so take a look at the channels, and it seems
[03:53.710 --> 03:59.710]  that video and audio is okay. So we'll do a quick demonstration on how
[04:02.110 --> 04:11.570]  we can write to these storage locations. All right, so that's with and without the
[04:11.570 --> 04:19.130]  front overlay. And to write to this, the antenna is on the back. So we're going to
[04:19.130 --> 04:26.430]  need to align the antenna from the back with a reader device, which typically is a
[04:26.430 --> 04:35.030]  smartphone. All right, in order to use the radio, to be able to use NFC, you have to
[04:35.030 --> 04:41.630]  turn the phone on, and it has to be at some accessible screen for the users, right? So
[04:41.630 --> 04:46.610]  it can't be turned off. That's the first thing you need to do in order to use the
[04:46.610 --> 04:52.990]  badge over radio. The next thing, you have to ensure that the NFC circuit is turned
[04:52.990 --> 05:01.670]  on. And that's right here. I can turn it off. And you need to have that turned on.
[05:01.670 --> 05:08.310]  All right, so those are the two things that you need. And after that, if you have nothing
[05:08.310 --> 05:17.150]  else happening, aside from what do we have? We have Discord and the Chrome browser running
[05:17.150 --> 05:25.630]  on my phone. So something should happen if I have programmed something to this device.
[05:26.130 --> 05:33.570]  And I align the antenna of the badge device to the phone. So I'm going to push the middle button
[05:33.570 --> 05:47.130]  there. And it brings up a web browser that's telling me that the data stored on this button,
[05:48.790 --> 05:55.050]  and in case you're curious, this is what the URL is on all of the middle buttons.
[05:57.920 --> 06:02.220]  All right, so that's reading data off of the device, off of the badge,
[06:02.220 --> 06:07.860]  this year's electronic badge, without really doing anything at all. This is right out of the box.
[06:09.160 --> 06:16.020]  What does the box look like? It looks like this. I don't know if this is so interesting,
[06:16.020 --> 06:22.940]  we'll do the unboxing. So you get a... so actually, this is a wrong manual for this box, but
[06:24.580 --> 06:32.940]  we got this excellent manual by Andres. And in some part, I discovered this just on my own.
[06:33.120 --> 06:40.960]  Let's see if we can... in fact, on the printed manual, his name isn't on here. Oh, yes, it is.
[06:40.960 --> 06:48.900]  In fact, there it is. So it's not so... so it's not so anonymous. I'm glad that he put his name
[06:48.900 --> 06:57.460]  on there. I thought he hadn't. So that comes in the box. Obviously, the different parts for a
[06:57.460 --> 07:02.560]  do-it-yourself model, you have to put it yourself together. You have to put... do it yourself,
[07:02.560 --> 07:07.980]  put it together. So the parts that do come assembled are all the very difficult things.
[07:07.980 --> 07:16.060]  That's these dome switches, which if you get three of them and you lose one,
[07:16.060 --> 07:20.880]  then you don't have enough. If you don't lose all three, you still have to align them perfectly well
[07:20.880 --> 07:27.380]  over the circuits and then place tape on top without anything moving more than a half millimeter.
[07:27.380 --> 07:32.840]  So it's just kind of messy and uncomfortable. On top of everything else, we knew that we would
[07:32.840 --> 07:37.760]  have to pre-assemble some of the parts anyway, because these EEPROMs, which we have already seen
[07:37.760 --> 07:45.160]  under the microscope, they're only two by three millimeters wide and they're one half millimeter
[07:45.160 --> 07:51.840]  tall also. So they're very, very small. That's why we're pre-assembling at least some of the parts
[07:52.820 --> 07:59.760]  which come in the do-it-yourself kit. All right. So that's what comes in the box. And after you
[07:59.760 --> 08:11.210]  take that out, you have something like this. You put it together, put the leather on the back,
[08:11.530 --> 08:17.530]  the color overlay on the front, and then you can start programming and doing just the same thing
[08:19.310 --> 08:26.690]  that I showed before. I will do that just once more in case you didn't completely see it.
[08:26.690 --> 08:33.350]  This time, there's nothing on the front. This time I'm going to show the action from the back.
[08:33.350 --> 08:39.350]  I'm going to align it over the antenna. I'm going to push down. Did you hear that?
[08:41.930 --> 08:47.550]  So that's how it sounds. And when I look at the front, well, it opened a web browser. Okay. Now
[08:47.550 --> 08:55.210]  I've got a whole bunch of web browsers. Yeah. Okay. So that's the reading right out of the box.
[08:55.210 --> 09:01.290]  Okay. Because we did pre... we programmed some of these identifiers onto these devices. There are
[09:01.290 --> 09:08.430]  three EEPROMs. And on each EEPROM, you have a variety of different slots, depending on how
[09:08.430 --> 09:15.270]  data, because they do have different capacities, these three EEPROMs. The first two are 512 bytes,
[09:15.270 --> 09:20.210]  and the last one is eight kilobytes. So depending on how much is there,
[09:20.210 --> 09:26.990]  you can do quite a lot of things. In fact, let's try using this program called NFC Tools.
[09:28.770 --> 09:34.410]  And I'm going to add several records. I'll try to do this very fast. Let's do
[09:37.050 --> 09:49.470]  Monero Village. Oops. Monero Village. I'm not spelling too well today.
[09:52.630 --> 10:00.050]  All right. We've got Monero Village. I'll put another URL on there for a pop quiz later on.
[10:02.750 --> 10:15.590]  Monero Devices. We'll put... we'll put a piece of text. We'll say this is...
[10:16.590 --> 10:28.890]  we'll just say DEF CON... DEF CON 28 safe mode. Do you like that? Okay. So we have some text.
[10:28.890 --> 10:34.210]  What else should we put on there? Somebody give me an idea. Here, take a look at all of these
[10:34.210 --> 10:42.940]  things. I'll help you choose. Quite a lot of different types of information, isn't it?
[10:43.440 --> 10:51.700]  Each one of these conforms with the NDEF standard. So that's what goes on NFC data storage.
[10:51.800 --> 10:57.320]  Every single one has a MIME type, which it's hiding from you because it's not a comfortable
[10:57.320 --> 11:05.300]  way to store information. It just tells you, okay, an address and there's a MIME type associated with
[11:05.300 --> 11:15.640]  this. So let's just say Iceland. That's a place, isn't it? I think so. All right. So that's a place.
[11:15.640 --> 11:22.460]  We'll add another one. We'll add a file link. I don't know how... I've never done file link. I
[11:22.460 --> 11:32.920]  don't know how that works. So let's do application. What's an easy one here? Email is really easy.
[11:33.560 --> 11:51.170]  We can do email. Info at MoneroDevices.com. And object. Oh, okay. It seems that
[11:51.650 --> 12:01.950]  that should say subject, shouldn't it? Dumb subject. I don't know why it says object there.
[12:02.350 --> 12:06.830]  And here we'll just type hello world. So we're putting an entire email,
[12:07.470 --> 12:13.890]  the headers and the body, hello email, I guess. So we've got all of these different pieces of data.
[12:13.890 --> 12:19.110]  Do you folks see that? I mean, I could keep going, right? I could... what's more options?
[12:20.390 --> 12:26.710]  So I could keep going and we would have 20, 30, 50 pieces of data here. And we can rearrange them.
[12:27.110 --> 12:34.450]  And what I wanted to show is that there are two URLs. So which one do you think will open a website?
[12:36.190 --> 12:43.870]  I mean, it's going to open a website if I write this to a village badge. And then let's do that
[12:43.870 --> 12:52.070]  now. Let's write. So now it's saying approach NFC tag. Do you see that? This is all quite
[12:52.070 --> 13:01.050]  self-evident, I think. So I'll turn the phone over. I'll align the badge onto the phone's
[13:01.050 --> 13:06.970]  antenna on the back. This time I will use the star button. Shall I do that?
[13:08.710 --> 13:13.850]  All right. So it's saying approach NFC tag. And now I'm going to click on the star.
[13:18.090 --> 13:21.970]  All right. Maybe you heard that. And it does say write complete.
[13:22.910 --> 13:25.830]  So what will happen now? If I close this application...
[13:28.750 --> 13:34.790]  Do I want to close this? Not really. Let's see what happens if I don't close it.
[13:34.790 --> 13:41.230]  So we're at the home screen, I suppose you call this. And I will,
[13:41.230 --> 13:45.450]  instead of clicking the second button, the moon there, I will click the star.
[13:49.570 --> 13:51.990]  So it does bring up a website.
[13:54.310 --> 13:57.400]  Monerovillage.org. Oh, I think it's... I think...
[13:59.150 --> 14:05.950]  I didn't use encryption. I just wrote HTTP, I think. Is that what it's complaining about?
[14:05.950 --> 14:11.450]  No. Monerovillage. What's wrong with this? I don't understand the problem.
[14:11.450 --> 14:17.230]  Okay. So here is a URI. Maybe it's because www is not correct.
[14:18.290 --> 14:21.710]  The point is that the web browser opened.
[14:23.850 --> 14:28.230]  Certificate date is invalid. Okay. So it seems that we have some problem with our website.
[14:28.230 --> 14:31.750]  It doesn't matter too much. What's important is that this badge
[14:31.750 --> 14:35.710]  opened automatically a website that we have programmed in by ourself
[14:38.430 --> 14:42.710]  onto this device, right? We can try this again.
[14:43.350 --> 14:49.710]  Looking back at the list of pieces of data, what happens now if I rearrange this?
[14:49.710 --> 14:53.930]  If this URI replaces the first one? Let's do that now, shall we?
[14:53.950 --> 14:58.750]  So I'm going to use the star again, but this is a different badge.
[15:00.990 --> 15:10.380]  So put that on the back there. And I will click...
[15:10.950 --> 15:35.460]  Why isn't it working yet? Could it be that another...
[15:35.460 --> 15:41.280]  So this is not working, is it? Let's try this one again. Let's try this one.
[15:46.860 --> 15:51.160]  So this time it worked. Not sure what happened with that other badge.
[15:53.260 --> 16:02.260]  And the test is to see what happens now when I use that one button and it will bring up a website.
[16:02.400 --> 16:09.500]  Okay, so that's the correct website now that we looked at, that we got before, right?
[16:09.500 --> 16:19.220]  So that's kind of the workflow of programming these and using them for day-to-day data storage.
[16:20.040 --> 16:25.860]  Right? MoneroVillage.com. Is that what AJ is saying?
[16:27.160 --> 16:31.060]  I thought it was .org. Have I been typing the wrong thing?
[16:32.620 --> 16:36.340]  All right, so AJ, sorry, I have to do this.
[16:38.760 --> 16:45.020]  This is my screen and it looks quite good. Oh, but okay, that's German. I'm sorry about that.
[16:45.700 --> 16:52.840]  No, you're right. So I've been typing org all these days and you're saying that I have to type
[16:52.840 --> 17:01.600]  com there? Then do I get a certificate? And it still says it's not secure.
[17:05.310 --> 17:11.730]  All right, so this is not the right time to troubleshoot and debug the website.
[17:14.520 --> 17:18.720]  But we did, however, we did just have a demonstration
[17:23.520 --> 17:31.360]  of how to program and use these badges on a day-to-day basis. So I can show you our application
[17:32.880 --> 17:39.640]  or homepage, I suppose you could call it, for this year's Village badge. How do I do that?
[17:39.640 --> 17:53.790]  I have to go back to this web browser. And because we were spending most of our time on the
[17:53.790 --> 18:06.920]  hardware, the software interface or the website, in other words, some of the parts are working
[18:06.920 --> 18:18.160]  and others aren't. So this is bobmonerodevices.com. This is with a good certificate.
[18:18.760 --> 18:23.300]  Okay, that's German, but it says a good certificate is fine. So we have two different
[18:23.300 --> 18:28.880]  menus here, one at the top that can toggle left to right, and one that goes up to down.
[18:29.800 --> 18:33.360]  And we've got some actions. I mean, this is a standard web application, right? We're not
[18:33.360 --> 18:42.020]  trying to make a whole operating system here. But the typical things like the about page,
[18:42.020 --> 18:46.620]  I guess this is good enough. It has all the information that you might expect.
[18:47.600 --> 18:51.920]  We have the welcome page there, which gives you an idea that you can use the badge
[18:51.920 --> 18:58.640]  on Android or iOS, because those two devices are smartphones with NFC circuits inside,
[18:58.640 --> 19:03.380]  and that NFC tools is the application that works.
[19:04.440 --> 19:09.820]  There's a few other things that work as well, like the game. I'll just click on game there on
[19:09.820 --> 19:18.100]  the left. It takes a bit to load. So we teamed up, Monero Village teamed up with the Rogues Village
[19:18.100 --> 19:27.460]  and a few others as well. And they programmed a game which works with the badge. I haven't got
[19:27.460 --> 19:33.920]  that far myself, but you can see there's a few people who have made it to the end. And
[19:34.660 --> 19:39.080]  the one thing that I don't like, if you just left click on the play button,
[19:39.080 --> 19:46.020]  so there's a cross side scripting problem, which it's not a problem. It's how the website is
[19:46.020 --> 19:57.440]  intended to work, but it's called CORS, C-O-R-S. And what you have to do is click on the right,
[19:58.940 --> 20:01.480]  and I mean, you can choose any of these things. I'm just saying,
[20:01.480 --> 20:04.740]  if I choose this, you won't see it. It's going to a different tab.
[20:06.180 --> 20:11.860]  All right. So what I'm going to do is copy the URL and then put it up here to show you
[20:11.860 --> 20:19.340]  what the game looks like. And this is the Rogues adventure game. There's a bunch of
[20:19.340 --> 20:26.360]  things to read about it here, but we will just kind of start playing. And although I haven't
[20:26.360 --> 20:31.300]  made it too far, according to our colleagues at the Rogue Village,
[20:31.300 --> 20:37.600]  it's about halfway through that you can use your electronic badge with this game.
[20:39.640 --> 20:42.720]  So I'll just type some random thing here.
[20:46.880 --> 20:51.540]  And so I'm not going to do this too long, but I'd like to give you some idea of how it works. So
[20:51.540 --> 20:58.520]  you can go down the stairs. I think there's something to look at here. Look at fossils.
[21:00.300 --> 21:09.180]  You get the idea, right? So this is kind of fun. Now, how do I go backwards?
[21:10.880 --> 21:18.440]  Oh, I can indeed change the tabs. All right. So that's one of the things that is working.
[21:18.440 --> 21:22.880]  Some other easy to implement things are working, like the gallery. I mean,
[21:22.880 --> 21:28.420]  this is not very valuable, but if you're interested in what the red one looks like,
[21:28.420 --> 21:34.120]  there it is. These are the different colors. And you've got the DIY to do it yourself. That's why
[21:34.120 --> 21:39.400]  there's no plastic enclosures. And you've got the different parts that you put together yourself.
[21:40.360 --> 21:47.020]  This is the wonderful user manual that Andres created for us. It's really nice.
[21:47.840 --> 21:51.920]  And this is kind of our experiment with the packaging, which we failed at last year. And
[21:51.920 --> 21:56.160]  this year we did pretty well, but we went overboard with that. So that's the gallery.
[21:56.160 --> 22:02.840]  We've got a file server where you can download the glossy color user manual. Well, it's not
[22:02.840 --> 22:09.640]  glossy. I don't know. Maybe I should take that off. It's not printed on paper when you download
[22:09.640 --> 22:15.700]  it electronically. So there's no gloss or matte finish. But you can get copies of either one.
[22:16.260 --> 22:21.320]  I'm not sure what happens if I click there, if it even works. You see, it does work.
[22:22.140 --> 22:27.020]  So there's Andres' design and all of the illustrations. Really wonderful work.
[22:27.740 --> 22:33.360]  So I'll go back and you can tell that the file server is working. We've got status,
[22:33.360 --> 22:36.260]  which is kind of halfway accurate. It just says there,
[22:36.260 --> 22:41.800]  application is undergoing development, which is true. We've got a top 10 FAQ.
[22:41.800 --> 22:48.720]  So I explained already why the playing of the game fails when you click on it.
[22:48.780 --> 22:53.700]  Which villages are participating? So none of this is all too exciting. What we actually
[22:53.700 --> 22:58.800]  really want, we start at the beginning here again. What we actually really want is here
[22:58.800 --> 23:04.020]  at the configure. No, I'm sorry, not the configure, but at the onboard. This is where it's going to
[23:04.020 --> 23:13.700]  get exciting because although it's not fully implemented to actually write the NDEF identifiers
[23:13.700 --> 23:20.080]  and pieces of data over radio. So we want to implement those things here and the way it will
[23:20.080 --> 23:28.340]  work. So you put your name here, any name at all. You could write, you could change the gender and
[23:28.980 --> 23:39.180]  geography. You can write you're some dead person. You could write, I am Alfred Nobel.
[23:41.000 --> 23:46.740]  So Alfred Nobel is no longer with us. What I'm just saying is that you can create a pseudonym
[23:46.740 --> 23:53.260]  here. All right. It's a nickname. After you put that in, you check off the things that you're
[23:53.260 --> 24:01.160]  interested in. So I like IOT. I like rogues a lot. And while that's too many, maybe I want
[24:01.160 --> 24:06.080]  biohacking as well. I won't be able to get them all on there because I'm programming the
[24:06.080 --> 24:11.380]  very small EEPROM. So I need to take some off. You get the idea. So I'm just going to be interested
[24:11.380 --> 24:17.780]  in this one round, rogues, Monero and biohacking. We'll click on associate me. And this is where
[24:17.780 --> 24:24.480]  it starts to not work. So even if I click on there, it's kind of these are not my choices.
[24:25.140 --> 24:30.060]  Yeah, you can see that this is still in prototype mode. So these are not my choices.
[24:32.280 --> 24:39.120]  But eventually we'll be able to write data or cancel. And it will start waiting for you to
[24:39.120 --> 24:44.960]  attach a badge or put a badge next to the antenna on the phone. If I want to do a factory reset,
[24:44.960 --> 24:52.660]  I can do that as well. And that's how this association and onboarding
[24:54.540 --> 24:59.900]  functionality will work. Once you have your identifiers on the EEPROMs all lined up like
[24:59.900 --> 25:05.040]  you'd like, you might want red team on the third EEPROM, you might want biohacking on the
[25:05.680 --> 25:11.200]  second one and crypto privacy and Monero you'll want maybe on the first one, whatever it is,
[25:11.200 --> 25:18.720]  you line these up and you write them to your badge. You can then use the intervillage network.
[25:19.320 --> 25:24.720]  Right. And although this looks okay, actually does look like it works. So it says here under
[25:24.720 --> 25:30.420]  development, please stay tuned. So it's not working yet. Okay. In the end, you can connect
[25:30.420 --> 25:36.060]  to the intervillage badge network by clicking on connect. You can do a ping just to test the
[25:36.060 --> 25:42.340]  network connection. If you need to authenticate, because for example, some of the village rooms
[25:42.340 --> 25:49.020]  or channels or topics are protected, maybe they would like to know who walks in through their
[25:49.020 --> 25:56.000]  doors, then you can authenticate. And if you don't need to, then you just skip that opcode or
[25:56.000 --> 26:04.720]  network code. You can turn on the bridge. I think the bridge will be activated by this command,
[26:04.720 --> 26:10.380]  safe mode, which basically means we're going to do a proxy from the MQTT network,
[26:10.380 --> 26:16.960]  which is what we're connected to here, to the DEF CON discord. I mean, this is kind of
[26:16.960 --> 26:23.300]  not relevant because they're probably going to turn off the DEF CON discord tomorrow. So there
[26:23.300 --> 26:29.820]  won't be much time to use it, but that's there just maybe for another day next year. So we can
[26:29.820 --> 26:34.940]  knock on one of the participating village's doors. We can knock on Monero's door.
[26:37.040 --> 26:41.160]  And if we don't get a response, we can knock again. And maybe on the third knock,
[26:41.160 --> 26:46.020]  we're automatically allowed to enter. There can be some logic like that.
[26:46.080 --> 26:53.140]  Once we're inside, we can tip using AJ's tip arrow, but one, two, four units.
[26:54.200 --> 26:59.620]  And once we're inside, we can get information about our room. Maybe we're walking in
[26:59.820 --> 27:04.800]  the biohacking room for the first time, and we didn't realize that there is a device program
[27:04.800 --> 27:09.940]  there, medical device program. We'd like to know more about the room that we walked in. We click
[27:09.940 --> 27:15.300]  on info. We can leave the room just as easily with the leave command and disconnect from the
[27:15.300 --> 27:22.040]  network with disconnect. All right. So that's kind of the rundown of the web application,
[27:22.040 --> 27:27.420]  which is under development. If we look at status, it says that clearly, application under development.
[27:28.120 --> 27:35.000]  Anybody who wants to help develop this, let me see how to...
[27:38.160 --> 27:44.360]  All right. So there is a URL to show. I've written it down some other place,
[27:44.360 --> 27:48.740]  but I'll never be able to find it. So I'll just reuse this piece of paper.
[27:48.740 --> 28:03.180]  Is everything going okay, AJ? So if you'd like to help to develop all of this web application
[28:03.180 --> 28:09.640]  logic, which is quite challenging, it's just tedious, lots of troubleshooting, firebug, and
[28:10.460 --> 28:17.080]  debugging, you can do a fork of the repository because it's all open source.
[28:17.080 --> 28:40.090]  The repository is found here. So this one is certainly calm. I know that because we don't
[28:40.090 --> 28:48.860]  have org. And we have a certificate. Everything's okay here. SCM stands for source code management.
[28:49.750 --> 28:55.470]  And if you do go there, then you can find all of our source code. Shall we take a look? Or are
[28:55.470 --> 29:02.010]  there questions about something else, some other topic? General text, office text. I don't see
[29:02.010 --> 29:07.070]  questions. So what we'll do, we'll take a look at the source code management system.
[29:07.710 --> 29:18.510]  How do I get back to that? Here it is. Okay, so now we will choose instead of BoB,
[29:21.360 --> 29:33.720]  let's go to SCM, shall we? And the nice thing about SCM is that it takes quite a long,
[29:33.720 --> 29:45.800]  long time to load because it's a very slow virtual server.
[29:46.620 --> 29:52.660]  VPS, virtual private server. All right. But in any case, we see that something did come up here.
[29:53.040 --> 29:58.680]  So instead of explaining all of these things and clicking through each one, which is a very
[29:58.680 --> 30:05.900]  slow process, I will just go right to apparatus, which is Esperanto for devices.
[30:08.180 --> 30:16.520]  And then we have a list of the different types of devices. Badges is here.
[30:17.520 --> 30:21.700]  And in the list of badges, we should see a few different things. And there is Monero
[30:21.700 --> 30:32.000]  Rising, Iron Triangle, which is the parent project of this derivative, the bush of being.
[30:32.000 --> 30:35.090]  And I think I should rename this, but the bush of being is the
[30:37.980 --> 30:44.680]  intervillage badge. So I just clicked on that. Let's navigate over to where the web application
[30:46.660 --> 30:57.870]  is found. It's under software. So there's a bit of things to read about here. The storyline,
[30:57.870 --> 31:05.250]  hardware, network. It's not up to date, but I think it's good enough explaining a few things.
[31:05.250 --> 31:09.470]  So right here in software, that's because it's obviously not hardware, graphics,
[31:09.470 --> 31:14.110]  enclosure, or documents. So if we have a web application, it's going to be listed under
[31:14.110 --> 31:19.710]  software. So I click there. We've got the website. So we may see other things here
[31:20.430 --> 31:28.130]  under software. We may have, you know, Android APK, not the APK itself, but the source code
[31:28.130 --> 31:34.250]  that builds the APK and whatever it's called for the Apple. I'm going to click on website.
[31:34.250 --> 31:39.490]  And then most people who are familiar with websites, you see the traditional CSS,
[31:39.490 --> 31:49.410]  the HTML5 and JavaScript CSS arrangement. So we've got documents. This is where Andres'
[31:51.630 --> 31:58.050]  user manuals are located inside the actual sources. And then we've got a few things. I
[31:58.050 --> 32:04.230]  think font awesome is in here as well. A few things like that. So here's the index. I don't
[32:04.230 --> 32:11.150]  think anything else is all that interesting. I'll just click on index to see what that looks like.
[32:11.930 --> 32:17.830]  And we're not going to drill down too deep, but this very last level is just kind of maybe
[32:18.610 --> 32:25.230]  interesting for some reason. This is all the source code. Oh, my. And it's just not interesting
[32:25.230 --> 32:35.050]  at all. Okay. So we do have some snippets. And you can navigate through this SCM source
[32:35.050 --> 32:39.430]  code management on your own because it is public site. You can fork, pull, and
[32:41.130 --> 32:53.020]  fetch sources. You can do merge requests. And I certainly hope that you do as well,
[32:53.020 --> 32:58.300]  because we could use a help. I mean, there's few of us doing work on this. So that's why
[32:58.300 --> 33:06.000]  we're kind of behind on things like the web application. So AJ says it all is good. I'm
[33:06.000 --> 33:13.200]  happy about that. We have another 20 minutes or so. What should I do now? So yesterday,
[33:13.200 --> 33:21.600]  what I said I would demonstrate was the impersonation is going to be a bit difficult,
[33:21.600 --> 33:28.680]  but I said I would demonstrate a passive capture. It's not data theft, because these are my own
[33:28.680 --> 33:35.720]  devices. So it's like opening the drawers to your shirt drawer. You're not stealing your
[33:35.720 --> 33:42.080]  shirts when you do that in your own house, right? So that's why I can take my own data
[33:42.080 --> 33:48.040]  and everything is just fine. If you do this without your own data, it's just not okay at all.
[33:48.160 --> 33:56.600]  So what I have here is a very nice box of chocolates. I wish the light was a bit better.
[33:59.180 --> 34:03.000]  I'm going to try to adjust the lights a bit. I'm not sure if that helps.
[34:07.420 --> 34:11.360]  I don't know if that helps. So I've got a nice box of chocolate here.
[34:12.420 --> 34:18.720]  And first thing what I will do is prepare this, because I forgot to turn something on.
[34:19.000 --> 34:25.680]  All right, and that's the other camera angle. That's about the size of the box of chocolates.
[34:29.030 --> 34:35.970]  And that's the way a box of chocolate sounds, isn't it? I don't know if you heard that. So
[34:35.970 --> 34:42.030]  remove this cover. Open this up. What do you think is inside? You want to take a guess?
[34:43.930 --> 34:49.470]  No, you don't want to guess? I'll show you. Okay, so that's these chocolates are inside.
[34:54.310 --> 34:56.950]  No, no, they're definitely chocolates.
[34:59.010 --> 35:11.830]  All right. Okay, so I've eaten almost all of them. I'm sorry, I didn't leave any for you.
[35:16.830 --> 35:27.710]  So what do you think will happen once we put this lid on the chocolate again?
[35:29.510 --> 35:36.470]  And let me just do that. I should have prepared this beforehand. Sorry about that.
[35:39.500 --> 35:46.300]  All right, so we've got the box of chocolates. I'm now going to place... let me just do this
[35:46.980 --> 35:56.320]  a different way. I'm going to place a library card on the box of chocolates.
[35:56.320 --> 36:00.960]  The contrast is very bad because it's a blue library card and blue chocolates. I'm
[36:00.960 --> 36:08.760]  sorry about that. I couldn't change the colors quickly. All right, so here's a library card.
[36:10.900 --> 36:17.620]  And I'm just going to drop that on there. Not sure if you heard that. If you didn't,
[36:17.620 --> 36:28.740]  I will put my microphone next to that box of chocolates. So I think you heard it that time.
[36:30.000 --> 36:35.980]  What I just did is capture data off of my library card. All right, so here I'm looking at the data
[36:35.980 --> 36:41.980]  now because if this wasn't my own data, and if it was a credit card instead of a library card,
[36:41.980 --> 36:49.060]  or say a passport, I'm not sure what types of cards and devices have this kind of circuit inside.
[36:49.060 --> 36:55.760]  But this one, as we can see, is a MyFair. So it's an ISO 14443. This is an RFID standard.
[36:56.320 --> 37:01.160]  And we just captured the data, right? The good news is that it's encrypted.
[37:01.160 --> 37:07.980]  You can tell that because it's got an ATQA and an SAK. But the serial number is there and you can
[37:08.720 --> 37:17.520]  certainly see some things, right? So what is this number? ISO 14443. Let's just do one more thing.
[37:19.160 --> 37:23.180]  How shall I do this? I'm going to capture the data off of my
[37:23.180 --> 37:28.300]  InterVillage badge now. And I will demonstrate that
[37:30.280 --> 37:34.460]  it's very difficult to trick your InterVillage badge in the same manner
[37:36.260 --> 37:42.840]  for one reason, because it has passive data theft protection built in. All right, so this is the
[37:42.840 --> 37:49.640]  screen. You can see that it's empty. I'm now going to try to capture the data in the same way.
[37:49.640 --> 37:55.780]  And just dropping it on there, it does nothing. It's impossible to capture the data. All right,
[37:55.780 --> 38:01.140]  I'm going to align the antenna. There is no problem. The device is perfectly well aligned
[38:01.140 --> 38:06.520]  on top of the turned on smartphone, which is capturing right now. It's reading.
[38:07.160 --> 38:16.440]  The reason that it does not successfully capture the data passively in this manner,
[38:16.440 --> 38:22.780]  would be known as theft, is that I have not pushed on one of the three buttons. And once I do that,
[38:22.780 --> 38:28.540]  as long as the screen is still turned on, once I do that, we should hear it capture.
[38:28.760 --> 38:39.100]  So let me go back here. All right, so I think you heard that. It did capture something as I
[38:39.100 --> 38:44.000]  was pushing down on there. Let's see what it captured. So I got all the data off of my
[38:44.000 --> 38:51.100]  intervillage badge, that thing. And the good news about that, so it's a different ISO standard. If
[38:51.100 --> 38:57.520]  we want to use the ISO 14443, like the library card was, and I just need to use
[38:59.460 --> 39:08.880]  a different button, right, because we have 15693 on these two, and the sun is a 14443 standard,
[39:08.880 --> 39:15.260]  which is my fair. So we can basically copy the data off of this library card
[39:15.800 --> 39:20.700]  onto this badge. All right, it is encrypted, which makes it more difficult, but some
[39:20.700 --> 39:27.980]  library cards are not encrypted. So some of the things to understand about that, it did
[39:27.980 --> 39:35.000]  successfully copy the data or capture it, right? If this is a box of chocolates that's unopened,
[39:35.000 --> 39:39.640]  you would not know that this is happening. And you can do this with a number of daily objects
[39:39.640 --> 39:49.380]  like magazines, newspapers, you can embed a reader into a table itself at a coffee shop.
[39:49.380 --> 39:55.220]  I think you understand the point. So today and tomorrow, yesterday and forever, there are
[39:58.260 --> 40:04.100]  people stealing data, and we wouldn't know it. And that's what makes it important to have a
[40:04.100 --> 40:11.400]  sense of, not a sense, to have a technical circuit built in which disconnects the antenna
[40:12.300 --> 40:18.880]  when you're not pushing on this. When a human is not pushing on one of the three buttons,
[40:19.540 --> 40:26.560]  this antenna is not connected to the ICs, the integrated circuits, which are storing the data.
[40:27.020 --> 40:32.200]  And what that means is that it's nearly impossible, it could possibly, it might not be
[40:32.200 --> 40:37.420]  impossible, I just don't want to say that, but it's very difficult, it's very, very difficult
[40:38.740 --> 40:43.820]  to capture data off of these things unless you're pushing on a button. And what I call that is
[40:44.840 --> 40:51.200]  defense of passive data theft. Is that what you call it too? Need money? Are you watching?
[40:52.060 --> 40:57.380]  All right, so we just demonstrated the passive data theft protection.
[40:58.340 --> 41:07.180]  And we demonstrated the writing of information. We demonstrated the passive capture of a library
[41:07.180 --> 41:16.680]  card. We demonstrated the difficulty of copying encrypted information. And we saw a nice chocolate
[41:16.680 --> 41:24.880]  box demonstration. And what else do we have? So there are a variety. What I like to experiment
[41:24.880 --> 41:35.300]  with are these types of transit cards are quite often, they either have a copper smart card
[41:37.780 --> 41:42.340]  integrated circuit, or they have an antenna inside, you can't see it then.
[41:43.100 --> 41:47.100]  And here's one, for example, with an antenna inside.
[41:47.100 --> 41:51.820]  How about this? Let's do another test. I will turn on this smartphone again.
[41:57.440 --> 42:01.380]  So we'll get this working again. And we've got this turned on. Remember, it's always very
[42:01.380 --> 42:06.720]  important to have your screen turned on. Otherwise, the NFC circuit, a lot of the radios don't work.
[42:07.060 --> 42:11.360]  All right, so this is an empty screen. There is no data on the screen. We're now going to
[42:14.400 --> 42:23.120]  passively copy data off of a transit card. Shall we do that? All right, so I'll just drop it on there.
[42:23.860 --> 42:27.420]  And if you heard that, it's already, it's too late.
[42:27.420 --> 42:35.140]  If I was not the owner, then I would have just lost the information. So what we have here,
[42:35.140 --> 42:40.700]  this is an interesting memory model. It's a MIFARE again. So you would see the 14443.
[42:41.260 --> 42:48.480]  Has a serial number, it has memory information. So this is quite interesting.
[42:50.680 --> 42:58.540]  On the pro model, it dumps the memory. On this one, it doesn't.
[42:59.380 --> 43:03.340]  But in any case, so we just captured the data from a transit card.
[43:04.880 --> 43:09.560]  All right, so that's how that works. What else can we demonstrate?
[43:12.290 --> 43:19.510]  You can take a quick look at what the devices look like from start to finish.
[43:22.680 --> 43:31.460]  During the manufacturing. So the manufacturing starts with a etched circuit board like this.
[43:32.800 --> 43:38.440]  Get the light a bit better. The light's not...
[43:41.940 --> 43:47.320]  Yeah, the lighting is just not very good. But so I'm not happy about that. And then there's a
[43:47.320 --> 43:53.240]  shadow if I do that. Okay, so this is the PCB or printed circuit board. And if you take a quick
[43:53.240 --> 44:03.010]  look, there are no parts on there. You can see the three different footprints.
[44:05.050 --> 44:12.810]  U1, U2, U3. There's no switches on the switch. SW1, SW2, SW3.
[44:14.890 --> 44:21.210]  So that's how we start. The other side needs to be flush and straight. So we don't have parts on
[44:21.210 --> 44:26.670]  at all. Because it needs to be right up against the reader device in some situations.
[44:26.750 --> 44:36.770]  So we begin by populating parts on this side. So I'm going to show a different PCB now.
[44:36.770 --> 44:42.490]  There they are side by side. And the one doesn't have parts and this one does. Okay,
[44:42.490 --> 44:48.630]  so what does that look like? After we populate the PCB with switches, with EPROMs, with integrated
[44:48.630 --> 44:57.230]  circuits, that's what it looks like then. There we go, focused. So we've got the three switches
[44:57.230 --> 45:03.270]  on there. We've got a piece of Kapton tape on top to keep them in place. And then we've got
[45:03.270 --> 45:11.870]  our EPROMs. Two of which are holding data in NDEF type 4. I'm sorry, NDEF type 5. And the last one,
[45:12.550 --> 45:20.830]  U3, is holding data in the format of NDEF type 4. That's my fair one. All right, now the other
[45:20.830 --> 45:26.230]  side is just the same. Because like I said before, in some cases, we need this antenna to be right up
[45:26.230 --> 45:34.550]  against the reading device. And for this reason, we can't put parts there. And the next step in
[45:34.550 --> 45:41.190]  the procedure to populate or to create these devices and assemble them is to place an overlay
[45:41.190 --> 45:47.250]  on the front and a piece of leather on the back for protection. All right, so what does that look
[45:47.250 --> 45:56.140]  like? The overlays look like this. So that's what it's like when... I'll just use one here.
[45:57.300 --> 46:04.360]  So that's what it looks like when we have placed the overlay, which has an adhesive
[46:05.440 --> 46:10.580]  back on it. Peel the adhesive back on and put the overlays on. And you can see that through
[46:10.580 --> 46:14.560]  the overlay, there are windows, transparent windows that show you the parts underneath
[46:14.560 --> 46:22.200]  the small chips. The other side of the badge, because we're going to be... so this is hard
[46:22.200 --> 46:27.380]  to see because it's black, but in this case, it's red. This is where we differentiate the
[46:27.380 --> 46:34.480]  colors in the villages. Monero obviously has an orange one. And the reason that leather is on
[46:35.020 --> 46:40.980]  so that when you put this against the phone, that it's not scratching your lens.
[46:41.220 --> 46:45.860]  Okay, so there's a functional purpose for this leather. Most people think that it's
[46:45.860 --> 46:51.600]  decorational. I mean, it does feel good, but it's actually there to protect the lens of your
[46:51.600 --> 46:56.460]  reading device, which is usually a smartphone. All right, so that's the front and the back.
[46:56.460 --> 47:01.760]  And once we do that, all we need to do to finish the device is to put it inside a
[47:02.980 --> 47:09.620]  enclosure frame. The reason this has two stripes is that they come out of the printer like this.
[47:09.620 --> 47:17.780]  It needs supports in between those two protruding pieces of the model. And that's why we put some
[47:17.780 --> 47:26.060]  supports in between. And one problem that we found is that every 10th badge that we assemble,
[47:26.060 --> 47:34.160]  we break the frame on it. So that's one reason we're not enclosing frames with the do-it-yourself
[47:34.160 --> 47:39.680]  models, because it would just be too much of a... we would need to supply two, three,
[47:39.680 --> 47:45.360]  four frames for each badge to make sure to ensure that the person didn't break it.
[47:45.980 --> 47:49.640]  All right, so that frame goes on the edge of the badge, as you can imagine.
[47:50.560 --> 47:55.560]  And it covers part of the leather to keep that on, and the edge is no longer...
[47:57.080 --> 48:00.980]  well, let me... I mean, this doesn't look good when you don't have...
[48:01.900 --> 48:06.160]  when you don't have that plastic on. You can see the different layers.
[48:06.660 --> 48:10.740]  So that's kind of a decorational thing. I do suppose that if you drop the badge,
[48:10.740 --> 48:16.320]  that the plastic frame does help a bit there as well. So you could call it a protectional feature.
[48:17.100 --> 48:24.500]  All right, so that's... I just realized that I forgot to record this. I'm supposed to record...
[48:25.140 --> 48:31.460]  okay, now it's too late. We're five minutes or 10 minutes away from the end. Okay, I forgot. Sorry.
[48:32.480 --> 48:40.680]  Right, so this is what happens when you fully create the badge. We have some black ones,
[48:40.680 --> 48:47.570]  which are called... the model number is called Black Matter. Black Matter. More narrow orange.
[48:49.560 --> 48:58.020]  We've got some Attack Red. Red on the back and on the front. We've got Defense Blue.
[48:59.580 --> 49:02.300]  The Defense Blue is quite nice. It's very translucent.
[49:04.200 --> 49:08.320]  You can see right through the plastic in some areas.
[49:08.320 --> 49:15.280]  This is what's so nice about SLA stereolithography. It's much more difficult to get a FDM or Fused
[49:15.280 --> 49:22.240]  Deposition Modeling process translucent. Anyway, so these are all the colors. I think there's a
[49:22.240 --> 49:28.840]  green one as well. And then we have some unique village colors. Let me show a couple of those.
[49:28.840 --> 49:37.400]  This one belongs to the Rogues Village. Colors do not... I don't know if maybe I can...
[49:38.940 --> 49:44.980]  I think it's a lighting problem. In any case, this is blue. You can't tell that it's blue.
[49:45.420 --> 49:51.320]  With a white frame. And they chose this because these are the colors of the Rogues Village.
[49:52.380 --> 49:56.060]  They chose the symbols as well. We got a lot of help from the Rogues Village.
[49:56.060 --> 50:00.140]  Really appreciate that. Thanks, folks, at the Rogues Village. This is the biohacking
[50:00.660 --> 50:06.040]  color scheme that they chose and reserved for their village. Because in biohacking, they have
[50:06.040 --> 50:12.260]  black and green. And so, as you can imagine, the front is the same on all of these.
[50:12.400 --> 50:18.340]  Translucent green frame. You can really see through that, can't you? And the back is black.
[50:18.340 --> 50:23.740]  So, I don't need to go through all of these because there are five or six different ones.
[50:24.340 --> 50:29.720]  But that's kind of how they look. And so, with five minutes left,
[50:29.720 --> 50:34.460]  I would just invite questions. And if there are no questions, we can either
[50:35.960 --> 50:43.500]  finish early or I can maybe look for some more. Oh, I know what I forgot. I wrote this in the
[50:43.500 --> 50:51.860]  description for this presentation. What I forgot is to show other badge types. So,
[50:51.860 --> 50:59.000]  as a prototype, this is kind of how we were developing before we got far enough to release
[50:59.000 --> 51:06.360]  the design. So, we have some wires soldered on there and extra button up here, which is a
[51:08.240 --> 51:16.040]  different tactile strength. Here, these are 260 grams. And this one up here is only 130, I think.
[51:16.040 --> 51:23.900]  And different parts. These are M24SRLR04. And the back looks very similar. So, this is a
[51:23.900 --> 51:33.120]  prototype board. Here is the Monero Rising. This is quite nice. I soldered a header on there for the
[51:33.820 --> 51:39.020]  SAO connection. And basically, how these work, it comes with a battery.
[51:40.280 --> 51:47.840]  And you turn it on and off on the side here. And when you turn it on, it lights up.
[51:48.300 --> 51:52.540]  Obviously, because there are a lot of LEDs on here. So, let's see what that looks like on the
[51:52.540 --> 52:03.040]  front. Now, we'll turn it on. All right. So, that flash is a... it's kind of a negotiation. It says
[52:03.040 --> 52:08.820]  I've turned on. It's indicating that the badge is ready for action. So, there are three capacitive
[52:08.820 --> 52:12.720]  touch buttons on the bottom here. They're not tactile. They're capacitive touch, which means I
[52:12.720 --> 52:22.350]  just lightly put my finger on the middle one to turn it on and off. So, now it's on. I have to be
[52:22.350 --> 52:27.790]  careful when I'm using the buttons because they are very sensitive. So, pressing them from the
[52:27.790 --> 52:33.890]  back is possible as well. Let's see if I can do that. Okay. It's not so easy, as easy as I thought.
[52:33.890 --> 52:39.350]  But if I push the same button again, it turns it off. You understand how that works? Once it turns
[52:39.350 --> 52:45.350]  it on, once turns it off. So, that's the on off button. The buttons to the side, left and right,
[52:45.350 --> 52:49.850]  these change the animation. Some of you already know this because we've produced quite a lot of
[52:49.850 --> 52:55.970]  these badges and a lot of people took them home last year. So, I will move to the second animation.
[53:00.100 --> 53:03.240]  Here's the third animation. So, I can go back to the first.
[53:04.500 --> 53:10.520]  And in all cases, when I switch the animation, I have to rest my finger on there long enough for
[53:10.520 --> 53:17.140]  it to complete the entire animation cycle. If I just do a quick tap, it will not read. Okay. Well,
[53:17.140 --> 53:23.760]  then it did, but you get the idea. Unless I'm touching that button at the very end,
[53:23.760 --> 53:30.140]  it won't register. All right. So, that's how the animations work.
[53:30.720 --> 53:35.720]  You can switch. You can turn this on and off with the middle. Turn it back on.
[53:37.360 --> 53:43.280]  Turn it off. Turn it on. So, that's how these things work. The one that I like the most,
[53:43.280 --> 53:48.940]  it's the very first one. I think it's starry night or sparkle. I can't remember the name.
[53:48.940 --> 53:58.200]  These animations have names. Yeah. I wish Mitty Poet was here because he did the firmware design
[53:58.200 --> 54:03.240]  and engineering and called these things what they look like, like the starry night.
[54:03.240 --> 54:09.460]  And we're close to finished with the badge clinic for today, but I hope that some of this
[54:09.460 --> 54:14.940]  information was helpful. Once again, I will turn it over just to show the back in case you're
[54:14.940 --> 54:24.790]  curious. That's how it looks. I could put this under the microscope, but anything larger than
[54:24.790 --> 54:32.050]  this very small part on the end under the microscope, it doesn't, you can't tell,
[54:32.050 --> 54:39.030]  it doesn't help because the microscope is too powerful. So, this is what this badge looks like.
[54:39.030 --> 54:45.690]  It has, I think, 100, between 120 and 140 parts. I've forgotten the actual number.
[54:46.350 --> 54:51.410]  You turn it on and off with a switch on the right here. Be careful with this switch. You
[54:51.410 --> 54:58.750]  don't want to push down while you're, it's good to be careful with it. It has bent off in some
[54:58.750 --> 55:03.270]  situations and you have to bend it back. So, I'll just turn it off there. And that's the hardware on
[55:03.270 --> 55:10.910]  off switch. All right. So, we're five minutes until the next presentation, which I believe is,
[55:10.910 --> 55:20.370]  let's just check that out, unless AJ wants me to stop or I don't know if we have a next presenter.
[55:21.210 --> 55:33.360]  Let's just check this out. MoneroVillage.org.com. I really, I don't know. I'm going to do org.
[55:33.720 --> 55:40.820]  Okay. So, this is not TLS protected, but in this moment, I'm not so concerned.
[55:41.380 --> 55:44.340]  So, let's see who's doing the next presentation.
[55:47.800 --> 55:51.960]  We have Badge Clinic is what's happening right now.
[55:54.160 --> 56:00.680]  And so, in one half hour, we're going to hear from Ruben.
[56:01.880 --> 56:06.040]  Giving competition to Monero by ditching opt-in privacy.
[56:07.880 --> 56:12.380]  All right. So, this looks very interesting. This appeals to me quite a lot.
[56:13.080 --> 56:19.020]  It's always nice to know what other cryptocurrencies are doing and how that relates
[56:19.020 --> 56:27.240]  and contrasts with our technology here at the Monero Village. And we actively welcome all the
[56:27.240 --> 56:31.940]  cryptocurrencies in the world, including the one you just made five minutes ago with your Python
[56:31.940 --> 56:40.780]  module, right? Your Python library. So, this is what we do at Monero Village, right?
[56:41.340 --> 56:46.120]  Anything that's blockchain related, cryptocurrency, things like that, you're welcome to
[56:46.920 --> 56:52.900]  ask questions about it or just come by and explain your project. We have that with Loki
[56:52.900 --> 56:59.180]  Mesh as well today. Really interesting stuff. And in the next presentation, which is coming in just
[56:59.180 --> 57:06.820]  one half hour, it will be from a Zcoin enthusiast and developer, I believe. So, that looks really
[57:06.820 --> 57:13.800]  good. So, I'm going to say goodbye. And I hope that you liked all of these devices.
[57:13.800 --> 57:22.620]  These badges, I think are sold out for the do-it-yourself models because people seem to
[57:22.620 --> 57:28.080]  like those quite a lot. But I do have this stack right here, plus a few others of the
[57:28.600 --> 57:37.220]  pre-assembled model. So, if you're interested in an attack red, a defense blue, you can get that.
[57:37.220 --> 57:43.120]  I'll write the URL here as well, just in case you're not sure where to find them. And with
[57:43.120 --> 57:57.560]  that, we will turn off the stream. So, the URL is shop.monerodevices.com. That's where you can
[57:57.560 --> 58:09.320]  still get your badge. Does that sound good? Need money? Are you watching now? Are you watching,
[58:09.320 --> 58:16.760]  Scott? Who's watching besides myself? All right. So, that's all for today. This was the badge
[58:16.760 --> 58:23.960]  clinic, the last badge clinic of the year 2020. Well, you know, we could be in China for...
[58:24.560 --> 58:31.000]  I'm not sure about that. They canceled China. But that was the badge clinic for DC28. And
[58:31.540 --> 58:37.240]  thanks a lot to the AV folks for helping. AJS, you did a great job and Justin as well.
[58:37.240 --> 58:46.140]  Okay. So, I will say goodbye. And that's it for me. My name is Michael. I'm MSVB.
[58:46.400 --> 58:48.180]  Have a good one and thanks for listening.
